Automatic current breaker

Abstract

The invention discloses an automatic current breaker and belongs to the field of heating of electric heaters. The automatic current breaker comprises insulating walls, microswitches and a tilt switch.The microswitches and the tilt switch are in series connection with a power circuit of the electric heater in sequence. The first insulating wall is mounted in a port of a water outlet pipe of an electric heater in a threaded connection mode, and the second insulating wall is mounted in a port of a water inlet pipe of the electric heater in a threaded connection mode. The first microswitch and the second microswitch are both normally open microswitches. The first microswitch is arranged at the bottom of the water inlet pipe, and the second microswitch is arranged at the bottom of the water outlet pipe. According to the automatic current breaker, by arranging the microswitches at the bottoms of the water inlet pipe and the water outlet pipe correspondingly, reliable connection between theelectric heater and the insulating walls is guaranteed, meanwhile, the tilt switch arranged inside can guarantee that the electric heater is in a vertical state, and the situation that tilting causesinternal water accumulation and affects the using safety of the electric heater is avoided.

Description

technical field [0001] The invention belongs to the heating field of electric heaters, in particular to an automatic power-off device. Background technique [0002] In the prior art, electric water heaters are generally heated by electric heating tubes, and the controller controls the temperature and cuts off the power. When the water temperature drops to the set temperature, the thermostat restarts the heating tubes for heating. Hidden danger. In recent years, although an automatic power-off shower device for cutting off the power supply has been invented, it is relatively complicated to control the power-off structure with a mechanical structure, and a large current is required to start when the heating tube is reheated, which brings certain limitations to the device. However, it cannot meet the automatic power-off requirements of high-end electric water heaters. How the automatic power-off device can make the user use hot water without electricity has become a new subje...
